Will brainlist!!! 21 and 22 form a linear pair.
If mZ1 = (5x + 9) and mZ2 = (3x + 11)", find m21.
mZ1 = 71°
m21 = 109°
mZ1 = 70°
m21 = 110°

3< x< 5

step-by-step explanation:

|x - 4| < 1

there are two solutions, one positive and one negative.   remember to flip the inequality when taking the negative solution

x-4 < 1       x-4 > -1

add 4 to each side

x-4+4 < 1+4       x-4+4 > -1+4

x< 5                 x> 3

3< x< 5

a triangular prism is a 3 dimensional shape composed of triangles and rectangles. it is made from two triangular bases and three rectangular sides.  

the answer is:
